chore: depr vendor and leverage nimble

[darshankabariya]

• Removed all submodules except the native ones still required (nim-ffi, zerokit, waku-rlnv2-contract, nph).
• Day-to-day commands (make wakunode2, make test, etc.) remain unchanged.
• we no longer need nimbus-build-system.
• Update CI according.
• latest version of all submodule
• Plan to replace the remaining four vendor libraries with nimble packages and delete ./vendor entirely.

closes #3672

instead of installing nim, it makes more sense to install nimble and have nimble manage nim.

Nim itself also needs to be locked down for a reproducible build.

[arnetheduck]

also, for a reproducible build, you need to lock the nimble version, which setup-nimble-action allows you to do.

[arnetheduck]

using requires this way will effectively prevent third-parties from depending on waku, unless they use the exact same commit of everything.

nimble lock can be used to produce a lock file that allows an application to use a locked set of deps while at the same time allowing others that depend on waku to be more flexible in the versions they use. For example, an application might want to use a newer version of chronicles for logging, and it's unreasonable for waku to limit this.

[darshankabariya]

Thanks for the idea. I’m now using nimble.lock to get an exact replica of the packages for the waku build.

@darshankabariya FYI in this #3670 I bumped versions on nim-chronos and nim-libp2p which involves new deps: nim-lsquic and nim-jwt.
These changes comes with some code adjustments. I suggest later incorporate these changes into this PR.

Sure, will do. I tried earlier, but it failed. I need to resolve the conflict carefully now.
